Redirect When Search Query Only Returns One Match

Be careful when using this, as users may not expect this functionality.

If there’s only one match for a particular search query, you can save users the hassle of clicking by simply redirecting them to the page/post.

add_action('template_redirect', 'single_result');
function single_result() {
	if (is_search()) {
		global $wp_query;
		if ( $wp_query->post_count == 1 && $wp_query->max_num_pages == 1 ) {
			wp_redirect( get_permalink( $wp_query->posts[0]->ID ) );
			exit;
		}
	}
}

Redirect When Search Query is an Exact Title Match

You probably shouldn’t use this if you have really generic page/post titles, but it can be a really handy feature.

Basically, if a user searches for something that happens to be an exact match to a page or post you have, it’ll redirect the user to the page, rather than displaying search results.

add_action('template_redirect', 'seach_query_is_title');
function seach_query_is_title() {
	if (is_search()) {
		global $wp_query;
		if ( get_page_by_title( get_search_query(), 'OBJECT', 'post' ) ) {
			wp_redirect( get_permalink( get_page_by_title (get_search_query() )->ID ) );
		}
		elseif ( get_page_by_title( get_search_query(), 'OBJECT', 'page' ) ) {
			wp_redirect( get_permalink( get_page_by_title( get_search_query() )->ID ) );
		}
	}
}
